Description

Technical Field

[0001] The present invention relates to the technical field of display panels, and in particular to a display panel and a display device. Background Art

[0002] With the continuous development of display technology, display panels have been widely used in people's production and life. However, there are still some technical problems in the display panels in the prior art that need to be solved urgently.

[0003] For example, users have a demand for full screens. However, most existing display panels have holes in the display area, resulting in a low screen-to-body ratio or black holes in the display area, which affects the display effect. Summary of the invention

[0004] The present invention provides a display panel and a display device to increase the screen-to-body ratio of the display panel and realize a full screen.

[0005] According to one aspect of the present invention, there is provided a display panel, comprising: a display area and a first area located in the display area;

[0006] The display area includes a substrate, a pixel defining layer, a plurality of light emitting elements and a light shielding layer which are arranged in sequence, the pixel defining layer has a plurality of first openings, the light shielding layer has a plurality of second openings, and the light emitting elements are located at the first openings;

[0007] The light shielding layer in the first area further has at least one third opening;

[0008] Along a first direction, the second opening overlaps with the first opening, and the third opening does not overlap with the first opening. The first direction is parallel to a stacking direction of film layers in the display area.

[0009] According to another aspect of the present invention, a display device is provided, comprising: the display panel as described above.

[0010] In the present invention, the display area includes a first area, and the light shielding layer in the first area has at least one third opening; along the first direction, the third opening does not overlap with the first opening, and the third opening is a structure that does not block light, so the area defined by the third opening in the first area is a newly added light-transmitting area, which allows light to pass through the third opening, thereby increasing the transmittance of the first area; since only a new opening, namely the third opening, is dug in the light shielding layer in the first area, the increase in the visible light reflectance of the first area is very small, and the third opening will not cause a serious dark state visual effect in the first area. Based on this, digging a new third opening in the light shielding layer in the first area can improve the transmittance of the first area, and the third opening has little effect on the display effect of the display panel, and can also ensure that the screen-to-body ratio of the display panel is high, realize a full screen, and improve the display effect.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0044] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0045] Figure 1 is a schematic diagram of a display panel provided by an embodiment of the present invention, Figure 2 is a schematic diagram of another display panel provided by an embodiment of the present invention. This embodiment can be applied to any display panel to improve transmittance. Figure 1 and Figure 2 As shown, the display panel includes: a display area 101 and a first area 102 located in the display area 101; the display area 101 includes a substrate 103, a pixel defining layer 104, a plurality of light-emitting elements 105 and a light-shielding layer 106 arranged in sequence, the pixel defining layer 104 has a plurality of first openings 107, the light-shielding layer 106 has a plurality of second openings 108, and the light-emitting element 105 is located in the first opening 107; the light-shielding layer 106 in the first area 102 also has at least one third opening 109; along the first direction A11, the second opening 108 overlaps with the first opening 107, and the third opening 109 does not overlap with the first opening 107, and the first direction A11 is parallel to the film layer stacking direction in the display area 101. Specifically, Figure 2, a partial cross section of the display panel along the first direction A11 is shown, including a third opening 109 and corresponding second openings 108 and first openings 107 .

[0046] In this embodiment, the display panel includes a display area 101 , and the display area 101 is used to display images.

[0047] The display panel includes a substrate 103, wherein the substrate 103 is a multi-layer stacking structure, and the specific film layer structure of the substrate 103 is not described in detail in this embodiment, and the first direction A11 is parallel to the film layer stacking direction in the substrate 103, and the first direction A11 and the second direction A12 intersect. Here, the first direction A11 and the second direction A12 may intersect perpendicularly.

[0048] The display panel includes a pixel defining layer 104, and the pixel defining layer 104 is located on one side of the substrate 103 along the first direction A11. In the display area 101, the pixel defining layer 104 has a plurality of first openings 107, and the plurality of first openings 107 correspond to a plurality of light-emitting elements 105, and the light-emitting elements 105 are located at the corresponding first openings 107. Specifically, the light-emitting elements 105 fill the corresponding first openings 107, and along the first direction A11, the optional light-emitting elements 105 cover the corresponding first openings 107, and the first openings 107 define the light-emitting areas of the corresponding light-emitting elements 105. The optional pixel defining layer 104 is a black pixel defining layer (BPDL), and the black pixel defining layer is made of a black material, which can reduce the reflection of light inside the display panel and improve the display effect. However, it is not limited to this. If the product requires, the pixel defining layer can also be a non-black pixel defining layer.

[0049] The display panel includes a plurality of light-emitting elements 105, and the plurality of light-emitting elements 105 can be divided into three categories, namely, a plurality of first light-emitting elements, a plurality of second light-emitting elements, and a plurality of third light-emitting elements. The colors configured for the first light-emitting element, the second light-emitting element, and the third light-emitting element can be different. Exemplarily, the first light-emitting element can be a red light-emitting element, the second light-emitting element can be a blue light-emitting element, and the third light-emitting element can be a green light-emitting element. However, it is not limited thereto. Relevant practitioners can reasonably configure the colors of the first light-emitting element, the second light-emitting element, and the third light-emitting element according to the requirements of the product. The colors of the first light-emitting element, the second light-emitting element, and the third light-emitting element can be the same, can be not completely the same, can be completely different, and so on.

[0050] The display panel includes a light shielding layer 106, which is located on the side of the pixel defining layer 104 away from the substrate 103, and the light shielding layer 106 can block light. In the display area 101, the light shielding layer 106 has a plurality of second openings 108, and the second openings 108 are structures that do not block light. The plurality of second openings 108 correspond to a plurality of light-emitting elements 105. Along the first direction A11, the orthographic projection of the second opening 108 on the pixel defining layer 104 overlaps with the corresponding first opening 107. Specifically, it is optional that along the first direction A11, the orthographic projection of the second opening 108 on the pixel defining layer 104 covers the corresponding first opening 107, and the light emitted from the light-emitting area of ​​the light-emitting element 105 defined by the first opening 107 can be emitted from the second opening 108. The optional shading layer 106 is a black matrix (BM), which is made of black material and can reduce the reflection of light inside the display panel, block the large-angle light emitted by the light-emitting element 105, and block external light from entering the display panel, thereby improving the display effect.

[0051] It can be understood that there are other film structures between the substrate 103 and the pixel defining layer 104, and there are other film structures between the pixel defining layer 104 and the light shielding layer 106. Figure 2 Not shown in the figure, some film layers will be described in detail in the subsequent embodiments.

[0052] The display area 101 includes a first area 102, and the area outside the first area 102 in the display area 101 is defined as a second area 110. The display area 101 is used for display, and the corresponding first area 102 can display, and the second area 110 can display. The distribution density of the light-emitting elements 105 in the second area 110 can be the same as or different from the distribution density of the light-emitting elements 105 in the first area 102, and the arrangement mode of the plurality of light-emitting elements 105 in the second area 110 can be the same as or different from the arrangement mode of the plurality of light-emitting elements 105 in the first area 102. Specifically, the distribution density of the light-emitting elements 105 in the second area 110 can be greater than or equal to the distribution density of the light-emitting elements 105 in the first area 102, and / or, the arrangement mode of the light-emitting elements 105 in the second area 110 can be the same as the arrangement mode of the light-emitting elements 105 in the first area 102. Figure 1 The mark 102 shown in FIG. 1 is an orthographic projection of the first area 102 along the first direction A11 .

[0053] The light shielding layer 106 in the first area 102 has at least one third opening 109; along the first direction A11, the third opening 109 does not overlap with the first opening 107. The third opening 109 is a structure that does not block light. Along the first direction A11, the area defined by the third opening 109 constitutes an additional light-transmitting area. Therefore, at least one third opening 109 is added to the light shielding layer 106 in the first area 102. Light passes through the third opening 109, which can increase the transmittance of the first area 102. Specifically, the transmittance of the opening area of ​​the conventional light shielding layer in the infrared light band (such as 940nm) is greater than 80%, and the transmittance of the non-opening area in the infrared light band is less than 2%. In this embodiment, one or more third openings 109 are added to the original non-opening area of ​​the light shielding layer 106 in the first area 102, so that the area ratio of the opening area of ​​the light shielding layer 106 in the first area 102 is increased, and the transmittance of the third opening 109 in the infrared light band is greater than 80%, so the transmittance of the infrared light band of the first area 102 can be effectively increased. Since the first area 102 only has a new opening, namely the third opening 109, in the original non-opening area of ​​the light shielding layer 106, the total area of ​​the newly added third opening 109 accounts for a very small proportion in the first area 102, and the corresponding visible light reflectivity of the first area 102 increases very little, and the first area 102 will not have a serious dark state visual effect, so that a good display effect of the display panel can be guaranteed. In this embodiment, the first area 102 can be selected as an IR hole.

[0054] It can be understood that the infrared light band is about 760nm to 1000nm, and the specific value of the infrared light transmittance described in the present invention is mainly the transmittance detected at 940nm. Exemplarily, the transmittance of the third opening 109 in the infrared light band is greater than 80%, which actually means that the transmittance of the third opening 109 at 940nm is greater than 80%.

[0055] Specifically, any one of the first opening 107, the second opening 108 and the third opening 109 includes an upper opening, a lower opening and an inner sidewall connecting the upper opening and the lower opening, wherein the upper opening is far from the substrate 103 and the lower opening is close to the substrate 103. In general, the inner sidewall of the opening has an inclined structure, and accordingly, the cross-sectional shape of the opening along the first direction A11 should be an inverted trapezoid, that is, the upper opening is larger and the lower opening is smaller, and specifically, the upper opening area of ​​the opening is larger than the lower opening area. Figure 1 The mark 107 shown in FIG. 1 is the orthographic projection of the lower opening of the first opening 107 along the first direction A11 , and the area defined by the lower opening of the first opening 107 is the light emitting area of ​​the corresponding light emitting element 105 . Figure 1 The mark 108 shown in FIG. 1 is the orthographic projection of the lower opening of the second opening 108 along the first direction A11 , and the area defined by the lower opening of the second opening 108 is the light-transmitting area of ​​the corresponding light-emitting element 105 . Figure 1The figure shows the overlapping relationship between the first opening 107 and the second opening 108 , and does not represent the actual size relationship. The relationship between the two can be designed to be greater than, less than or equal to each other according to product requirements. Figure 1 The mark 109 shown in the figure is the orthographic projection of the lower opening of the third opening 109 along the first direction A11. The area defined by the lower opening of the third opening 109 is the newly added light-transmitting area of ​​the first area 102, which is not used to transmit the light emitted by the light-emitting element 105.

[0056] The optional first region 102 includes: a first functional device 201 located on a side of the substrate 103 away from the light shielding layer 106; along the first direction A11, at least one third opening 109 overlaps the first functional device 201. Here, the optional first functional device 201 includes an optical device.

[0057] Optical devices may be provided in the first area 102 to increase the screen-to-body ratio and meet the user's full-screen needs. For example, optical devices such as a camera, a face recognition sensor, a fingerprint recognition sensor, and an infrared light sensor may be provided in the first area 102 .

[0058] In this embodiment, the first area 102 can be selected as an IR hole, and the first functional device 201 can be selected as an infrared light sensor, which can receive and send infrared light. The first area 102 can display normally, and at least one third opening 109 is added to the light shielding layer 106 of the first area 102, which can also improve the light transmittance of the first area 102 and increase the light passing through the first area 102, so that the first area 102 can realize the light transmission function, meet the photosensitivity requirements of the optical device in the first area 102, and improve the optical detection accuracy of the optical device.

[0059] It should be noted that the shape of the first area 102 in the display panel can be circular, oval, square, or other shapes. Figure 1 The shape of the first area 102 is circular. The shape of the optional third opening is polygonal or circular, but not limited thereto. The shape of the exemplary third opening can also be elliptical, square, or other shapes. Figure 1 In the example, the shape of the third opening 109 is an ellipse.

[0060] In the present invention, the display area includes a first area, and the light shielding layer in the first area has at least one third opening; along the first direction, the third opening does not overlap with the first opening, and the third opening is a structure that does not block light, so the area defined by the third opening in the first area is a newly added light-transmitting area, which allows light to pass through the third opening, thereby increasing the transmittance of the first area; since only a new opening, namely the third opening, is dug in the light shielding layer in the first area, the increase in the visible light reflectance of the first area is very small, and the third opening will not cause a serious dark state visual effect in the first area. Based on this, digging a new third opening in the light shielding layer in the first area can improve the transmittance of the first area, and the third opening has little effect on the display effect of the display panel, and can also ensure that the screen-to-body ratio of the display panel is high, realize a full screen, and improve the display effect.

[0061] Figure 3 is a schematic diagram of another display panel provided by an embodiment of the present invention, Figure 4 yes Figure 3 A partial top view of the first zone in the figure, Figure 3 and Figure 4 The optional display area 101 shown also includes: a color resist layer 111 located on the side of the light shielding layer 106 away from the pixel defining layer 104, the color resist layer 111 includes a first color filter 112, a second color filter 113 and a third color filter 114; the second opening 108 includes a first color filter opening 115, a second color filter opening 116 and a third color filter opening 117, the first color filter 112 is at least located in the first color filter opening 115, the second color filter 113 is located in the second color filter opening 116, and the third color filter 114 is located in the third color filter opening 117. Figure 4 Any one of the second opening 108 and the third opening 109 shown in FIG. 1 , specifically the lower opening thereof.

[0062] In this embodiment, the display panel further includes a color resist layer 111, and the color resist layer 111 includes a plurality of color filters. The plurality of color filters can be divided into three categories, namely, a plurality of first color filters 112, a plurality of second color filters 113, and a plurality of third color filters 114. The colors of the first color filter 112, the second color filter 113, and the third color filter 114 are configured differently. The first color filter 112 can be a red color filter; the second color filter 113 can be one of a green color filter and a blue color filter, and the third color filter 114 can be the other of a green color filter and a blue color filter. Exemplarily, the first color filter 112 is a red color filter, the second color filter 113 is a blue color filter, and the third color filter 114 is a green color filter. Exemplarily, the first color filter 112 is a red color filter, the second color filter 113 is a green color filter, and the third color filter 114 is a blue color filter. However, the present invention is not limited thereto, and relevant practitioners may reasonably configure the colors of the first color filter, the second color filter, and the third color filter according to product requirements.

[0063] At least one of the first color filter 112 , the second color filter 113 , and the third color filter 114 may be circular in shape. Figure 4 The shapes of the first color filter 112, the second color filter 113 and the third color filter 114 are all circular, but are not limited thereto.

[0064] In the light shielding layer 106, the plurality of second openings 108 include a plurality of first color filter openings 115, a plurality of second color filter openings 116, and a plurality of third color filter openings 117. The first color filter 112 is at least located in the first color filter openings 115, the second color filter 113 is located in the second color filter openings 116, and the third color filter 114 is located in the third color filter openings 117. Specifically, the first color filter 112 at least fills the corresponding first color filter openings 115, and along the first direction A11, the first color filter 112 covers the corresponding first color filter openings 115; the second color filter 113 at least fills the corresponding second color filter openings 116, and along the first direction A11, the second color filter 113 covers the corresponding second color filter openings 116; the third color filter 114 fills the corresponding third color filter openings 117, and along the first direction A11, the third color filter 114 covers the corresponding third color filter openings 117. Along the first direction A11 , the second opening 108 covers the corresponding first opening 107 , so the light emitted by the light emitting element 105 can be emitted through the corresponding color filter and have the color characteristics of the color filter.

[0065] In this embodiment, the third opening 109 of the light shielding layer 106 is a structure that does not block light, and along the first direction A11, the first functional device 201 overlaps with at least one third opening 109 in the first area 102. The transmittance of the third opening 109 at 940nm is greater than 80%, and the infrared light emitted by the first functional device 201 can be emitted through the third opening 109, or external light (specifically infrared light) can be incident on the first functional device 201 through the third opening 109, and the first area 102 can realize the infrared light transmission function through the third opening 109.

[0066] Figure 5 is a schematic diagram of another display panel provided by an embodiment of the present invention, Figure 6 yes Figure 5 A partial top view of the first zone in the figure, Figure 5 and Figure 6 An optional first color filter 112 is also shown located in the third opening 109 . Figure 6 Any one of the second opening 108 and the third opening 109 shown in FIG. 1 , specifically the lower opening thereof.

[0067] In this embodiment, at least one third opening 109 is filled with a first color filter 112. The first color filter 112 may be a red color filter. When the first color filter 112 fills the third opening 109, the third opening 109 can transmit infrared light. Specifically, the third opening 109 has a high transmittance of 940 nm. The addition of the third opening 109 in the first area 102 can improve the infrared light transmittance and meet the infrared light transmittance requirements of the product. The third opening 109 filled with the first color filter 112 also has a blocking effect on visible light.

[0068] The optical device optionally provided in the first area 102 includes an infrared distance sensor. Along the first direction A11, the infrared distance sensor overlaps with at least one third opening 109 and at least one second opening 108. The opening area in the light shielding layer 106 allows infrared light to pass through. The infrared distance sensor senses infrared light through the infrared light emitting tube and the infrared light receiving tube therein, thereby measuring the distance between the display device and the target object (such as a face, a finger, etc.), and then controls the screen of the display device to be turned on or off according to the distance.

[0069] In the first area 102, a third opening 109 is added, and a first color filter 112 is filled in the third opening 109, which can improve the infrared light transmittance of the first area 102. While ensuring the normal display of the first area 102, the first area 102 can also achieve infrared transmission function, which is conducive to realizing a full screen.

[0070] It should be noted that, in the case where the third opening 109 is filled with a color filter, the third opening 109 in the first area 102 meets the requirements of transmitting infrared light and blocking visible light. Based on this, in subsequent embodiments, if the third opening 109 is filled with a color filter, the light emission, light incidence, light transmission requirement, transmittance, etc. of the first area 102 and / or the third opening 109 all refer to infrared light emission, infrared light incidence, infrared light transmission requirement, infrared light transmittance, etc.

[0071] In the display panel, the first area 102 includes a plurality of third openings 109, and at least one third opening 109 is filled with a first color filter 112, then the first area 102 can realize the infrared light transmission function, and an optical device for sensing infrared light can be provided in the first area 102. Alternatively, in the display panel, some of the third openings 109 are not filled with color filters, and some of the third openings 109 are filled with the first color filter 112, then the first area 102 may realize both the visible light transmission function and the infrared light transmission function, and according to product requirements, an optical device for sensing visible light (such as a camera) and / or an optical device for sensing infrared light (such as an infrared distance sensor) can be provided in the first area 102.

[0072] In this embodiment, if the third opening 109 is adjacent to the first color filter opening 115, the first color filter 112 may extend and simultaneously fill the third opening 109 and the first color filter opening 115. Alternatively, the same first color filter 112 may simultaneously fill at least one first color filter opening 115 and at least one third opening 109. Alternatively, the first color filter 112 filled in the first color filter opening 115 and the first color filter 112 filled in the third opening 109 are independent of each other.

[0073] It should be noted that, in the first zone 102, only one or more third openings 109 are newly dug in the light-shielding layer 106, and the first color filter 112 fills the third opening 109, so that the visible light transmittance of the third opening 109 is very small, and the corresponding reflectivity (R%) of the first zone 102 in the visible light range of 360 to 780 nm increases very little, and the first zone 102 will not have a serious dark state visual effect, thereby ensuring a good display effect of the display panel.

[0074] Figure 7 is a schematic diagram of another display panel provided by an embodiment of the present invention, Figure 8 yes Figure 7 A partial top view of the first zone in the figure, Figure 7 and Figure 8 The optional second color filter 113 is also shown in the third opening 109 ; along the first direction A11 , the first color filter 112 and the second color filter 113 overlap in the third opening 109 . Figure 8 Any one of the second opening 108 and the third opening 109 shown in FIG. 1 , specifically the lower opening thereof.

[0075] In this embodiment, the third opening 109 is filled with two color filters. Specifically, the third opening 109 is filled with a stacked second color filter 113 and a first color filter 112. The first color filter 112 can be a red color filter, and the third opening 109 can be used as an opening for transmitting infrared light. In the third opening 109, the overlapping area of ​​the second color filter 113 and the first color filter 112 can reduce the characteristics of external light incidence and reflection, further block visible light, improve the infrared light transmittance of the first area 102, and also enable the first area 102 to realize the infrared transmission function, which is conducive to realizing a full screen and improving the optical detection accuracy of the optical device of the first area 102.

[0076] In the optional third opening 109, the second color filter 113 is located between the first color filter 112 and the pixel defining layer 104. Figure 7 As shown, the second color filter 113 is located between the first color filter 112 and the pixel defining layer 104. Under normal circumstances, most of the light emitted by the light emitting element 105 corresponding to the color filter will be emitted through the corresponding second opening 108, and light with a larger angle will be blocked by the light shielding layer 106.

[0077] In this embodiment, a third opening 109 is additionally provided in the light shielding layer 106. The large-angle light emitted by the light-emitting element 105 corresponding to the second color filter 113 may be incident on the adjacent third opening 109, and the first color filter 112 located above the second color filter 113 in the third opening 109 can block it, so as to prevent the large-angle light of the light-emitting element 105 corresponding to the second color filter 113 from being emitted and affecting the display effect, and to avoid problems such as light leakage and color cast on the display panel, thereby improving the display effect of the first area 102. Similarly, the large-angle light emitted by the light-emitting element 105 corresponding to the third color filter 114 may be incident on the adjacent third opening 109, and the second color filter 113 and the first color filter 112 in the third opening 109 can block it, so as to prevent the large-angle light of the light-emitting element 105 corresponding to the third color filter 114 from being emitted and affecting the display effect, and to avoid problems such as light leakage and color cast on the display panel, thereby improving the display effect of the first area 102.

[0078] As described above, if the third opening 109 is adjacent to the second color filter opening 116, the second color filter 113 may extend and simultaneously fill the third opening 109 and the second color filter opening 116. Alternatively, the same second color filter 113 may simultaneously fill at least one second color filter opening 116 and at least one third opening 109. Alternatively, the second color filter 113 filled in the second color filter opening 116 and the second color filter 113 filled in the third opening 109 are independent of each other.

[0079] Fig. 9 is a schematic diagram of another display panel provided by an embodiment of the present invention, Fig.10 yes Fig. 9 A partial top view of the first zone in the figure, Fig. 9 and Fig.10 As shown, for the third opening 109 , along the first direction A11 , the second color filter 113 covers the third opening 109 , and the first color filter 112 covers the second color filter 113 . Fig.10 Any one of the second opening 108 and the third opening 109 shown in FIG. 1 , specifically the lower opening thereof.

[0080] In this embodiment, at least one third opening 109 is filled with a stacked second color filter 113 and a first color filter 112. The second color filter 113 that optionally fills the third opening 109 is independent of the other second color filters 113, and along the first direction A11, the second color filter 113 covers the third opening 109, and the first color filter 112 covers the second color filter 113. In other words, the first color filter 112 completely covers the second color filter 113 in the third opening 109, and the second color filter 113 completely fills and covers the third opening 109. In this way, on the basis of satisfying the infrared transmission function of the third opening 109, the second color filter 113 and the first color filter 112 that completely cover the third opening 109 can block the large-angle light emitted by the light-emitting element 105 corresponding to the third color filter 114 from emitting from the third opening 109, and can also block the large-angle light emitted by the light-emitting element 105 corresponding to the second color filter 113 from emitting from the third opening 109, and can also block the transmission of visible light, thereby avoiding the problem of light leakage from the light-emitting element 105 from the third opening 109.

[0081] As described above, the first color filter 112 in the third opening 109 and the first color filter 112 in the first color filter opening 115 may be independent of each other, and the second color filter 113 in the third opening 109 and the second color filter 113 in the second color filter opening 116 may be independent of each other. However, this is not limited thereto.

[0082] It should be noted that, in the first zone 102, only one or more third openings 109 are newly dug in the light-shielding layer 106, and the stacked second color filter 113 and the first color filter 112 fill the third openings 109. Therefore, the third openings 109 basically do not transmit visible light. Compared with the second zone 110, the increase (ΔR%) of the visible light reflectivity of the first zone 102 is very small and can even be regarded as no increase. Therefore, the first zone 102 will not have a dark state visual effect, and can ensure the good display effect of the display panel.

[0083] Fig.11 is a schematic diagram of another display panel provided by an embodiment of the present invention, Fig.12 yes Fig.11 A partial top view of the first zone in the figure, Fig.11 and Fig.12 As shown, along the first direction A11 , the first color filter 112 covers at least one second opening 108 and at least one third opening 109 . Fig.12 Any one of the second opening 108 and the third opening 109 shown in FIG. 1 , specifically the lower opening thereof.

[0084] In this embodiment, a plurality of second openings 108 and a plurality of third openings 109 are formed in the light shielding layer 106, wherein the second color filter openings 116 of the second openings 108 are filled with the second color filter 113, and the third color filter openings 117 of the second openings 108 are filled with the third color filter 114. Optionally, along the first direction A11, the second color filter 113 fills the second color filter openings 116 and extends to cover a portion of the light shielding layer 106, and the third color filter 114 fills the third color filter openings 117 and extends to cover a portion of the light shielding layer 106.

[0085] The first color filter 112 is filled in other light shielding layer areas except the second color filter 113 and the third color filter 114, and the first color filter 112 fills the plurality of first color filter openings 115 and the plurality of third openings 109. In this way, the first area 102 can be used as an infrared light-transmitting area as a whole, so that one or more infrared light sensors with the same or different functions can be integrated in the first area 102, which is conducive to realizing the full screen and infrared light transmission functions.

[0086] It should be noted that, in the first area 102, only one or more third openings 109 are newly dug in the light-shielding layer 106, and the first color filter 112 fills the third opening 109. The first color filter 112 covers part or all of the light-shielding layer 106. Therefore, the reflectivity increase of the first area 102 in the visible light range of 360nm to 780nm is very small, and the first area 102 will not have a dark state visual effect, which can ensure the good display effect of the display panel.

[0087] Fig.13 is a schematic diagram of another display panel provided by an embodiment of the present invention, Fig.14 yes Fig.13 A partial top view of the first zone in the figure, Fig.13 and Fig.14 The second color filter 113 optionally located in the second color filter opening 116 is shown to extend to overlap with at least one third opening 109. In the optional first region 102, the orthographic projection area of ​​the light shielding layer 106 along the first direction A11 is Sa, and the orthographic projection area of ​​the first color filter 112 along the first direction A11 is Sb, and Sb / Sa≥50%. Fig.14 Any one of the second opening 108 and the third opening 109 shown in FIG. 1 , specifically the lower opening thereof.

[0088] In this embodiment, a plurality of second openings 108 and a plurality of third openings 109 are formed in the light shielding layer 106, wherein the second color filter opening 116 of the second opening 108 and at least one third opening 109 are filled with the second color filter 113, and the third color filter opening 117 of the second opening 108 is filled with the third color filter 114. Optionally, along the first direction A11, the same second color filter 113 fills the second color filter opening 116 and extends to fill at least one adjacent third opening 109, and the third color filter 114 fills the third color filter opening 117 and extends to cover a portion of the light shielding layer 106.

[0089] The same first color filter 112 is filled in the plurality of third openings 109 and the plurality of first color filter openings 115 of the light shielding layer 106, and the first color filter 112 in the third opening 109 is stacked on the second color filter 113. In this way, the first area 102 can be used as an infrared light-transmitting area as a whole, which is convenient for integrating one or more infrared light sensors with the same or different functions in the first area 102, and is conducive to realizing the full screen and infrared light transmission functions. In addition, the first color filter 112 and the second color filter 113 stacked in the third opening 109 can effectively block visible light.

[0090] It should be noted that, in the first zone 102, only one or more third openings 109 are newly dug in the light-shielding layer 106, and the stacked second color filter 113 and the first color filter 112 fill the third opening 109. The first color filter 112 covers part or all of the light-shielding layer 106. Therefore, the first zone 102 basically does not transmit visible light. Compared with the second zone 110, the increase in the visible light reflectivity of the first zone 102 is very small and can even be regarded as no increase. Therefore, the first zone 102 will not have a dark visual effect, which can ensure the good display effect of the display panel.

[0091] In the optional first zone, the area of ​​the orthographic projection of the light-shielding layer along the first direction is Sa, and the area of ​​the orthographic projection of the third opening along the first direction is Sc; Sc / Sa≤10%. For any of the above embodiments, Sc / Sa may be greater than or equal to 3% and less than or equal to 10%. In the first zone, if the area proportion of the third opening in the light-shielding layer is too large, it will occupy too much of the area proportion of the second opening in the light-shielding layer, thereby affecting the resolution of the first zone. In the first zone, if the area proportion of the third opening in the light-shielding layer is too small, it will affect the infrared light transmittance of the first zone, thereby affecting the working performance of the infrared light sensor integrated in the first zone, reducing its detection accuracy, and affecting the infrared sensing effect of the display panel. Therefore, the R&D personnel designed Sc / Sa≤10%, and the optional 3%≤Sc / Sa≤10%. Of course, depending on the application field of the display panel, relevant practitioners can reasonably design the Sc / Sa ratio according to product requirements without specific restrictions.

[0092] Optionally, along the first direction, the color filter film thickness of any one of the second opening 108 and the third opening 109 is greater than or equal to 2.5 μm and less than or equal to 4 μm. During the manufacturing process of the display panel, a high-transmittance CF process or a low-transmittance CF process can be selected according to the application requirements of the product, where CF (Color Filter) is the color filter in this embodiment. The film thickness of the color filter refers to the thickness dimension of the color filter in the opening along the first direction.

[0093] In this embodiment, when a high-transmittance CF process is selected based on the application requirements of the product, the film thickness of the color filter in the second opening 108 can be designed to be greater than or equal to 2.5 μm and less than or equal to 4 μm. Specifically, the second opening 108 includes a first color filter opening 115 filled with the first color filter 112, a second color filter opening 116 filled with the second color filter 113, and a third color filter opening 117 filled with the third color filter 114, wherein the color filter film thickness of any color filter opening is greater than or equal to 2.5 μm and less than or equal to 4 μm. Exemplarily, the first color filter 112 can be selected as a red color filter, the second color filter 113 can be selected as a blue color filter, and the third color filter 114 can be selected as a green color filter. It is found that the transmittance of the red color filter in the first color filter opening 115 is between 67% and 78%, the transmittance of the blue color filter in the second color filter opening 116 is between 71% and 80%, and the transmittance of the green color filter in the third color filter opening 117 is between 55% and 69%.

[0094] Specifically, the thickness range of the red filter is designed to be 2.5μm to 4μm. It is found that the transmittance of the red filter with a thickness of 2.5μm is about 78%. As the thickness of the red filter gradually increases to 4μm, the transmittance of the red filter decreases to 67%. Similarly, the thickness range of the blue filter is designed to be 2.5μm to 4μm. It is found that the transmittance of the blue filter with a thickness of 2.5μm is about 80%. As the thickness of the blue filter gradually increases to 4μm, the transmittance of the blue filter decreases to 71%. Similarly, the thickness range of the green filter is designed to be 2.5μm to 4μm. It is found that the transmittance of the green filter with a thickness of 2.5μm is about 69%. As the thickness of the green filter gradually increases to 4μm, the transmittance of the green filter decreases to 55%. Therefore, the smaller the thickness of a single color filter, the greater the transmittance, and the larger the thickness, the smaller the transmittance.

[0095] When a high-transmittance CF process is selected based on the application requirements of the product, the thickness of the color filter in the third opening 109 can be designed to be greater than or equal to 2.5 μm and less than or equal to 4 μm. Specifically, if the third opening 109 only includes the first color filter 112, the thickness of the first color filter 112 is greater than or equal to 2.5 μm and less than or equal to 4 μm. If the third opening 109 includes a first color filter 112 and a second color filter 113 stacked in a stacked arrangement, the sum of the thicknesses of the first color filter 112 and the second color filter 113 in the third opening 109 along the first direction is greater than or equal to 2.5 μm and less than or equal to 4 μm.

[0096] In the optional third opening 109, the film thickness of the first color filter 112 is different from the film thickness of the second color filter 113. In the optional third opening 109, the film thickness of the first color filter 112 is less than the film thickness of the second color filter 113. In the optional third opening 109, the film thickness of the first color filter 112 is greater than or equal to 0.7 μm and less than or equal to 2 μm. In the optional third opening 109, the film thickness of the second color filter 113 is greater than or equal to 2 μm and less than or equal to 3 μm.

[0097] As described above, for a single color filter, under the same film thickness (such as 2.5 μm), the transmittance of the green filter (69%), the transmittance of the red filter (78%), and the transmittance of the blue filter (80%) are arranged in order from small to large; similarly, for a single color filter, under the same transmittance (such as 78%), the film thickness of the green filter (less than 2.5 μm), the film thickness of the red filter (equal to 2.5 μm), and the film thickness of the blue filter (greater than 2.5 μm) are arranged in order from small to large. The first color filter 112 can be a red color filter, and the second color filter 113 can be a blue color filter. For the case where the third opening 109 includes a first color filter 112 and a second color filter 113 that are stacked, the film thickness of the first color filter 112 can be selected to be smaller than the film thickness of the second color filter 113. In this way, the difference between the transmittance of the first color filter 112 and the transmittance of the second color filter 113 in the third opening 109 can be reduced. It is even possible to eliminate the difference between the transmittance of the first color filter 112 and the transmittance of the second color filter 113 in the third opening 109 or to keep the difference within an allowable range by reasonably designing the film thickness of the first color filter 112 and the film thickness of the second color filter 113.

[0098] In addition, the film thickness of any one of the first color filter 112, the second color filter 113 and the third color filter 114 in the second opening 108 is designed to be greater than or equal to 2.5 μm and less than or equal to 4 μm. It is found that the color rendering index Re of the area where the second opening 108 is located is 6.62, the hue value a* is about -1.51, and the hue value b* is about -0.99. Taking the value of the area where the second opening 108 is located as the reference value (base), the difference of the reflectivity hue-related value of the area where the third opening 109 is located relative to the base is within the range of ±0.2, then the human eye will not recognize the difference between the third opening 109 and the second opening 108, and the human eye will not recognize the display difference between the second area 110 and the first area 102, indicating that the display effect of the display panel is good.

[0099] Based on this, by repeatedly adjusting the film thickness of the first color filter 112 and the second color filter 113 in the third opening 109, for the case where the third opening 109 includes a first color filter 112 and a second color filter 113 that are stacked, the film thickness of the first color filter 112 in the third opening 109 can be selected to be greater than or equal to 0.7 μm and less than or equal to 2 μm, and the film thickness of the second color filter 113 in the third opening 109 can be greater than or equal to 2 μm and less than or equal to 3 μm.

[0100] Exemplarily, for the case where the third opening 109 includes a first color filter 112 and a second color filter 113 that are stacked, the thickness of the first color filter 112 in the third opening 109 can be 0.7 μm and the thickness of the second color filter 113 can be 2 μm. Then, it is detected that the color rendering index Re of the area where the third opening 109 is located is 6.63, the hue value a* is about -1.45, and the hue value b* is about -1.20; or, the thickness of the first color filter 112 in the third opening 109 can be 1.5 μm. And the film thickness of the second color filter 113 is 3μm, then the detection finds that the color rendering index Re of the area where the third opening 109 is located is 6.62, the hue value a* is approximately -1.51, and the hue value b* is approximately -1.01; or, the film thickness of the first color filter 112 in the third opening 109 can be 1μm and the film thickness of the second color filter 113 is 2μm, then the detection finds that the color rendering index Re of the area where the third opening 109 is located is 6.62, the hue value a* is approximately -1.49, and the hue value b* is approximately -1.08.

[0101] It is found that if the thickness of the first color filter 112 in the third opening 109 is less than 0.7 μm and / or the thickness of the second color filter 113 is less than 2 μm, the difference between the hue value b* and the base exceeds the range of ±0.2. If the thickness of the first color filter 112 in the third opening 109 is greater than 2 μm and / or the thickness of the second color filter 113 is greater than 3 μm, the thickness of the color filter in the third opening 109 is too large, which affects the thinning. There may also be a situation where the difference between at least one of the hue values ​​a* or b* and the base exceeds the range of ±0.2.

[0102] Optionally, along the first direction, the color filter film thickness of any one of the second opening 108 and the third opening 109 is greater than or equal to 2.5 μm and less than or equal to 3.5 μm.

[0103] In this embodiment, when the low-transmittance CF process is selected based on the application requirements of the product, the film thickness of the color filter in the second opening 108 can be designed to be greater than or equal to 2.5 μm and less than or equal to 3.5 μm, and the film thickness of the color filter in the third opening 109 can be designed to be greater than or equal to 2.5 μm and less than or equal to 3.5 μm. In the case where the third opening 109 includes a single first color filter 112, the film thickness of the first color filter 112 is designed to be greater than or equal to 2.5 μm and less than or equal to 3.5 μm. In the case where the third opening 109 includes a first color filter 112 and a second color filter 113 that are stacked, the sum of the film thicknesses of the first color filter 112 and the second color filter 113 in the third opening 109 is greater than or equal to 2.5 μm and less than or equal to 3.5 μm.

[0104] For a single-color filter, when the film thickness is greater than or equal to 2.5μm and less than or equal to 3.5μm, detection found that the transmittance of the red filter is between 52% and 63%, the transmittance of the blue filter is between 57% and 67%, and the transmittance of the green filter is between 42% and 52%. The smaller the film thickness of the single-color filter, the greater the transmittance, and the greater the film thickness, the smaller the transmittance.

[0105] In the optional third opening 109, the film thickness of the first color filter 112 is different from the film thickness of the second color filter 113. In the optional third opening 109, the film thickness of the first color filter 112 is less than the film thickness of the second color filter 113. In the optional third opening 109, the film thickness of the first color filter 112 is greater than or equal to 1 μm and less than or equal to 2 μm. In the optional third opening 109, the film thickness of the second color filter 113 is greater than or equal to 1 μm and less than or equal to 3 μm. Exemplarily, the optional first color filter 112 is a red color filter and the second color filter 113 is a blue color filter.

[0106] In this embodiment, for the case where the third opening 109 includes a first color filter 112 and a second color filter 113 that are stacked, the film thickness of the first color filter 112 can be selected to be smaller than the film thickness of the second color filter 113. Then, the difference between the transmittance of the first color filter 112 and the transmittance of the second color filter 113 in the third opening 109 can be reduced. It is even possible to eliminate the difference between the transmittance of the first color filter 112 and the transmittance of the second color filter 113 in the third opening 109 or to be within an allowable range by reasonably designing the film thickness of the first color filter 112 and the film thickness of the second color filter 113.

[0107] In addition, the film thickness of any one of the first color filter 112, the second color filter 113 and the third color filter 114 in the second opening 108 is designed to be greater than or equal to 2.5 μm and less than or equal to 3.5 μm. It is found that the color rendering index Re of the area where the second opening 108 is located is 5.42, the hue value a* is about -0.07, and the hue value b* is about -1.11. Taking the value of the area where the second opening 108 is located as the reference value (base), the difference of the reflectivity hue-related value of the area where the third opening 109 is located relative to the base is within the range of ±0.2, then the human eye will not recognize the difference between the third opening 109 and the second opening 108, and the human eye will not recognize the display difference between the second area 110 and the first area 102, indicating that the display effect of the display panel is good.

[0108] Based on this, by repeatedly adjusting the film thickness of the first color filter 112 and the second color filter 113 in the third opening 109, for the case where the third opening 109 includes a first color filter 112 and a second color filter 113 that are stacked, the film thickness of the first color filter 112 in the third opening 109 can be selected to be greater than or equal to 1 μm and less than or equal to 2 μm, and the film thickness of the second color filter 113 in the third opening 109 can be greater than or equal to 1 μm and less than or equal to 3 μm.

[0109] For example, in the case where the third opening 109 includes a first color filter 112 and a second color filter 113 that are stacked, the thickness of the first color filter 112 in the third opening 109 may be 1 μm and the thickness of the second color filter 113 may be 1 μm, and then the detection finds that the color rendering index Re of the area where the third opening 109 is located is 5.43, the hue value a* is approximately 0.00, and the hue value b* is approximately -1.25; or, the thickness of the first color filter 112 in the third opening 109 may be 2 μm and the thickness of the second color filter 113 may be 1 μm. If the film thickness of the color filter 113 is 2μm, it is detected that the color rendering index Re of the area where the third opening 109 is located is 5.42, the hue value a* is about -0.07, and the hue value b* is about -1.12; or, the film thickness of the first color filter 112 in the third opening 109 is 1.5μm and the film thickness of the second color filter 113 is 3μm, then it is detected that the color rendering index Re of the area where the third opening 109 is located is 5.42, the hue value a* is about -0.07, and the hue value b* is about -1.14.

[0110] It is found that if the thickness of the first color filter 112 in the third opening 109 is less than 1 μm and / or the thickness of the second color filter 113 is 1 μm, at least one of the hue values ​​a* or b* may differ from the base by more than ±0.2. If the thickness of the first color filter 112 in the third opening 109 is greater than 2 μm and / or the thickness of the second color filter 113 is greater than 3 μm, the color filter thickness in the third opening 109 may be too large, which may affect the thinning. At least one of the hue values ​​a* or b* may differ from the base by more than ±0.2.

[0111] Fig.15 is a schematic diagram of another display panel provided by an embodiment of the present invention, Fig.16 yes Fig.15 A local top view of the pixel defining layer in FIG. Fig.15 and Fig.16 The optional pixel defining layer 104 shown includes: a first non-opening area 119; along the first direction A11, the orthographic projection of the third opening 109 is located in the first non-opening area 119. Fig.16 The cross-sectional structure of the pixel defining layer 104 along F11-F12 can be referred to Fig.15 The pixel defining layer 104 shown, Fig.16 The third opening 109 shown in the figure is actually the positive projection of the third opening 109 on the pixel defining layer 104. Exemplarily, the first opening 107 and the third opening 109 can be circular, but not limited thereto, and relevant practitioners can reasonably design the opening shapes of the first opening, the second opening, the third opening, etc. according to product requirements.

[0112] In this embodiment, the pixel defining layer 104 includes a plurality of first openings 107. Specifically, the first opening 107 includes an upper opening 120, a lower opening 121, and an inner sidewall 122 connecting the upper opening 120 and the lower opening 121. The area surrounded by the lower opening 121 is substantially the light-emitting area of ​​the corresponding light-emitting element 105. The pixel defining layer area outside the area surrounded by the upper opening 120 in the pixel defining layer 104 is the non-opening area of ​​the pixel defining layer 104, and the first non-opening area 119 is part or all of the non-opening area of ​​the pixel defining layer 104.

[0113] Along the first direction A11, the orthographic projection of the third opening 109 is located in the first non-opening area 119, and the orthographic projection of the third opening 109 does not overlap with the upper opening 120 of the first opening 107. That is to say, along the first direction A11, the pixel defining layer area corresponding to the orthographic projection of the third opening 109 is not opened, and the third opening 109 will not affect the light-emitting area of ​​the light-emitting element 105, thereby ensuring the normal display function of the display panel. And at least the first color filter 112 fills the third opening 109, and the first color filter 112 covers part or all of the light-shielding layer 106, so the first area 102 basically does not transmit visible light, so that the first area 102 meets the infrared light transmission requirements, and the first area 102 will not have an increase in reflectivity relative to other areas, and the corresponding first area 102 will not have a dark state visual effect, which can ensure a good display effect of the display panel.

[0114] Fig.17 is a schematic diagram of another display panel provided by an embodiment of the present invention, such as Fig.17 The optional pixel defining layer 104 shown includes: a plurality of first spacers 123; along the first direction A11, the third opening 109 does not overlap with the first spacer 123. Optionally, along the first direction A11, the first spacer 123 overlaps with the first non-opening area.

[0115] In this embodiment, the non-opening area of ​​the pixel defining layer 104 is provided with one or more first spacers 123, and the first spacers 123 are used to support the display panel in the first direction A11, and when the display panel is an organic light-emitting display panel, the first spacers 123 can also support the mask during the evaporation process. The projection of the structure of the first spacer 123 in the first direction A11 can be an ellipse, a circle, or a rounded rectangle, but is not limited thereto.

[0116] Along the first direction A11, the orthographic projection of the third opening 109 is located in the first non-opening area 119, the first spacer portion 123 is located in the non-opening area of ​​the pixel defining layer 104, and the third opening 109 does not overlap with the first spacer portion 123. If the first non-opening area 119 is a part of the non-opening area of ​​the pixel defining layer 104, the first spacer portion 123 may be located within the first non-opening area 119 along the first direction A11, or the first spacer portion 123 may partially overlap with the first non-opening area 119 along the first direction A11, or the first spacer portion 123 may be located outside the first non-opening area 119 along the first direction A11. If the first non-opening area 119 is the entire non-opening area of ​​the pixel defining layer 104, the first spacer portion 123 is located within the first non-opening area 119 along the first direction A11.

[0117] Relevant practitioners can reasonably design the distribution position and distribution density of the first spacer portion 123 in the non-opening area of ​​the pixel defining layer 104 according to product requirements, and are not specifically limited in the present invention. For example, taking a mobile phone of conventional size as an example, the non-opening area of ​​the pixel defining layer 104 of the display panel in the mobile phone is provided with the first spacer portion 123, and the shape of the first spacer portion 123 along the first direction A11 can be a square, and the size of the square can be 8.5μm*8.5μm.

[0118] refer to Fig.17 As shown, the optional display area further includes an active layer located between the substrate 103 and the light shielding layer 106; along the first direction A11, the third opening 109 does not overlap with the active layer.

[0119] In this embodiment, the display panel may be an organic light emitting display panel, but is not limited thereto.

[0120] The display panel includes a substrate 103 on which a thin film transistor array layer 202 is disposed. The thin film transistor array layer 202 includes a plurality of thin film transistors. The thin film transistor array layer 202 is a part of a pixel circuit structure and is used to drive the light emitting element 105 for display.

[0121] The thin film transistor array layer 202 includes a first active layer 203, and the first active layer 203 can be a poly layer, specifically a low temperature polycrystalline silicon LTPS layer. Along the first direction A11, the third opening 109 does not overlap with the first active layer 203, so that the light emitted by the first functional device 201 will not be blocked by the first active layer 203, so that the light emitted by the first functional device 201 can be emitted through the third opening 109; or, after passing through the third opening 109, the external light will not be blocked by the first active layer 203, so that the external light can be incident on the first functional device 201 through the third opening 109.

[0122] At present, the thin film transistor array layer 202 in some organic light-emitting display panels also includes a second active layer 204, and the second active layer 204 can be a metal oxide layer, specifically an indium gallium zinc oxide IGZO layer. The second active layer 204 can be located between the first active layer 203 and the pixel defining layer 104. Similarly, along the first direction A11, the third opening 109 does not overlap with the second active layer 204, so the light emitted by the first functional device 201 will not be blocked by the second active layer 204, or the external light will not be blocked by the second active layer 204 after passing through the third opening 109, so it is beneficial for the first functional device 201 to receive and send light through the third opening 109.

[0123] It should be noted that, along the first direction A11, the third opening 109 does not overlap with the active layer, thereby ensuring the infrared light transmission requirement of the first region 102, so that the first functional device 201 can work normally.

Fig.17 , Fig.18 and Fig.19 The optional multiple light-emitting elements 105 shown include a first color light-emitting element 124, a second color light-emitting element 125 and a third color light-emitting element 126; two first color light-emitting elements 124 and two second color light-emitting elements 125 constitute a first virtual quadrilateral 127, the first color light-emitting element 124 is located at the first vertex of the first virtual quadrilateral 127, the second color light-emitting element 125 is located at the second vertex of the first virtual quadrilateral 127, the first vertex and the second vertex in the first virtual quadrilateral 127 are alternately arranged, and the third color light-emitting element 126 is located inside the first virtual quadrilateral 127; four third color light-emitting elements 126 constitute a second virtual quadrilateral 128, the third color light-emitting element 126 is located at the vertex of the second virtual quadrilateral 128, and the first color light-emitting element 124 or the second color light-emitting element 125 is located inside the second virtual quadrilateral 128.

[0125] in, Fig.18 and Fig.19 The cross-sectional structure of the pixel defining layer 104 along F21-F22 can be referred to Fig.17 The pixel defining layer 104 shown, Fig.18 and Fig.19 The third opening 109 shown in the figure is actually the positive projection of the third opening 109 on the pixel defining layer 104. Fig.18 and Fig.19The light emitting element 105 shown is specifically the shape of the light emitting area of ​​the light emitting element 105, that is, the shape of the lower opening of the first opening 107. Exemplarily, the first opening 107 and the third opening 109 can be circular, but are not limited thereto.

[0126] The first virtual quadrilateral 127 may be in the shape of a regular quadrilateral such as a square, a rectangle, a parallelogram, or an irregular quadrilateral. Fig.18 The shape of the first virtual quadrilateral 127 formed by the two first color light emitting elements 124 and the two second color light emitting elements 125 is a rectangle. Fig.19 The shape of the first virtual quadrilateral 127 formed by the two first color light emitting elements 124 and the two second color light emitting elements 125 is an irregular quadrilateral. However, the present invention is not limited thereto. In other embodiments, the shape of the first virtual quadrilateral 127 changes accordingly according to the layout of the first opening 107 in the pixel defining layer 104.

[0127] The second virtual quadrilateral 128 may be in the shape of a regular quadrilateral or an irregular quadrilateral. Fig.18 The shape of the second virtual quadrilateral 128 formed by the four third color light emitting elements 126 is a rectangle. Fig.19 The shape of the second virtual quadrilateral 128 formed by the four third color light emitting elements 126 is an irregular quadrilateral. However, the present invention is not limited thereto. In other embodiments, the shape of the second virtual quadrilateral 128 changes accordingly according to the layout of the first opening 107 in the pixel defining layer 104.

[0128] In this embodiment, the light emitting area of ​​the optional light emitting element 105 (i.e., the lower opening of the first opening 107) is in a circular shape. However, the present invention is not limited thereto, and in other embodiments, the lower opening of the first opening may be in a shape of an irregular trapezoid, a regular trapezoid, an ellipse, a rounded rectangle, or other shapes.

[0129] refer to Fig.17As shown, along the first direction A11, the first color light emitting element 124 overlaps with the first color filter 112 in the first color filter opening 115, the second color light emitting element 125 overlaps with the second color filter 113 in the second color filter opening 116, and the third color light emitting element 126 overlaps with the third color filter 114 in the third color filter opening 117. After the light emitted by the first color light emitting element 124 passes through the first color filter 112, the emitted light is configured as red light; after the light emitted by the second color light emitting element 125 passes through the second color filter 113, the emitted light is configured as blue light; after the light emitted by the third color light emitting element 126 passes through the third color filter 114, the emitted light is configured as green light. Accordingly, the first color light emitting element 124 can be a red light emitting element, the second color light emitting element 125 can be a blue light emitting element, and the third color light emitting element 126 can be a green light emitting element. However, it is not limited to this, and relevant practitioners can reasonably configure the colors of the first color light-emitting element, the second color light-emitting element, and the third color light-emitting element according to product requirements. The colors of the three can be the same, not completely the same, completely different, and so on.

[0130] refer to Fig.18 or Fig.19 As shown, the orthographic projection of the optional third opening 109 along the first direction A11 is located between adjacent first color light emitting elements 124 and second color light emitting elements 125 .

[0131] In this embodiment, the distance between the first color light emitting element 124 and the second color light emitting element 125 in the non-opening area is relatively large. The distance between the first color light emitting element 124 and the third color light emitting element 126 in the non-opening area is relatively small, and the distance between the second color light emitting element 125 and the third color light emitting element 126 in the non-opening area is relatively small.

[0132] It can be seen that the gap between the first color filter opening 115 corresponding to the first color light emitting element 124 and the second color filter opening 116 corresponding to the second color light emitting element 125 is relatively large, and there is enough space to set the third opening 109 there, and the third opening 109 can also maintain a sufficient distance from the first color filter opening 115, the second color filter opening 116 and the third color filter opening 117. Accordingly, along the first direction A11, the orthographic projection of the third opening 109 is located between the adjacent first color light emitting element 124 and the second color light emitting element 125, and the orthographic projection of the third opening 109 can maintain a sufficient distance from the adjacent first color light emitting element 124 and the second color light emitting element 125, thereby reducing the risk of light emitted by the light emitting element 105 being emitted through the third opening 109.

[0133] refer to Fig.18 or Fig.19As shown, the optional first virtual quadrilateral 127 includes a first virtual side 129 and a second virtual side 130 connected to each other; the orthographic projection of the third opening 109 along the first direction A11 is located between the first color light emitting element 124 and the second color light emitting element 125 connected to the first virtual side 129 .

[0134] In this embodiment, the first virtual quadrilateral 127 includes four virtual edges connected sequentially, and two of the connected virtual edges are defined as a first virtual edge 129 and a second virtual edge 130 . Fig.18 In the embodiment, the shape of the first virtual quadrilateral 127 is a rectangle, and the first virtual side 129 and the second virtual side 130 connected in the first virtual quadrilateral 127 intersect vertically. Fig.19 In the embodiment, the shape of the first virtual quadrilateral 127 is an irregular trapezoid, and the first virtual side 129 and the second virtual side 130 connected in the first virtual quadrilateral 127 intersect.

[0135] The display panel includes a plurality of light emitting elements 105. A plurality of first color light emitting elements 124 and a plurality of second color light emitting elements 125 are alternately arranged along the extension direction of the first virtual side 129 to form a row of light emitting elements 105, and a plurality of rows of light emitting elements 105 are sequentially arranged along the extension direction of the second virtual side 130. A plurality of first color light emitting elements 124 and a plurality of second color light emitting elements 125 are alternately arranged along the extension direction of the second virtual side 130 to form a column of light emitting elements 105, and a plurality of columns of light emitting elements 105 are sequentially arranged along the extension direction of the first virtual side 129.

[0136] Along the first direction A11, the orthographic projection of the third opening 109 is located between the first color light emitting element 124 and the second color light emitting element 125 connected to the first virtual edge 129. Specifically, along the first direction A11, the orthographic projection of the third opening 109 overlaps with the first virtual edge 129; or, along the first direction A11, the orthographic projection of the third opening 109 is located on one side of the first virtual edge 129.

[0137] The optional pixel defining layer 104 includes: a plurality of first spacers 123 ; the first spacers 123 are located between adjacent first color light emitting elements 124 and second color light emitting elements 125 .

[0138] In this embodiment, the distance between the first color light-emitting element 124 and the second color light-emitting element 125 in the non-opening area is relatively large, so there is enough space to set the first pad portion 123 there, and it is also possible to maintain a sufficient distance between the first color light-emitting element 124, the second color light-emitting element 125 and the third color light-emitting element 126.

[0139] refer to Fig.18 or Fig.19As shown, there are two adjacent first color light emitting elements 124 and second color light emitting elements 125 , and a third opening 109 and a first spacer portion 123 may be disposed between the two.

[0140] Fig. 20 yes Fig.17 Another partial top view of the pixel defining layer in FIG. Fig. 20 As shown, the optional first virtual quadrilateral 127 includes a first virtual side 129 and a second virtual side 130 connected to each other; in the first region 102 , the first spacer portion 123 is located between the first color light-emitting element 124 and the second color light-emitting element 125 connected to the second virtual side 130 .

[0141] In this embodiment, the distance between the first color light emitting element 124 and the second color light emitting element 125 in the non-opening area is relatively large.

[0142] Optionally, a third opening 109 is provided between adjacent first color light emitting elements 124 and second color light emitting elements 125, or a first spacer portion 123 is provided between adjacent first color light emitting elements 124 and second color light emitting elements 125. That is, the third opening 109 and the first spacer portion 123 are not provided simultaneously between adjacent first color light emitting elements 124 and second color light emitting elements 125. Specifically, the third opening 109 may be provided between adjacent first color light emitting elements 124 and second color light emitting elements 125 along the extension direction of the first virtual edge 129; and the first spacer portion 123 may be provided between adjacent first color light emitting elements 124 and second color light emitting elements 125 along the extension direction of the second virtual edge 130. Optionally, the first spacer portion 123 overlaps with the second virtual edge 130 along the first direction A11; or, the first spacer portion 123 is located on one side of the second virtual edge 130 along the first direction A11.

[0143] Based on this, the first spacer portion 123 can maintain a sufficient distance from the first color light-emitting element 124, the second color light-emitting element 125 and the third color light-emitting element 126, and the orthographic projection of the third opening 109 can maintain a sufficient distance from the adjacent first color light-emitting element 124 and the second color light-emitting element 125.

[0144] The first spacer 123 can support the mask during the mask manufacturing process. If the first spacer 123 is too close to the first opening 107, the first spacer 123 may be squeezed by the mask and other tools during the mask manufacturing process and may easily fall into the first opening 107, forming a dark spot on the display and affecting the yield. In particular, the current display panel pursues high PPI, and in order to ensure the density of the first spacer 123, the size of the first spacer 123 cannot be compressed to the limit, which will result in a low panel yield. In the present embodiment, if a first spacer portion 123 is provided between adjacent first color light emitting elements 124 and second color light emitting elements 125, the third opening 109 will not be provided at the same time, so that there is enough space for the first spacer portion 123 to be provided therein, and the position of the first spacer portion 123 can be controlled to be away from the first opening 107. In this way, while ensuring the density of the first spacer portion 123, the risk of the first spacer portion 123 falling into the first opening 107 can be reduced, thereby improving the manufacturing yield and the display effect, and to a certain extent, the size of the first spacer portion 123 can also be increased to ensure the supporting effect.

[0145] refer to Fig. 20 As shown, optionally, along the direction of the first virtual edge 129 , the size of the third opening 109 is greater than or equal to the size of the first spacer portion 123 ; along the direction of the second virtual edge 130 , the size of the third opening 109 is greater than or equal to the size of the first spacer portion 123 .

[0146] When the display panel pursues a high PPI, the spacing between adjacent first openings 107 is small. If the size of the first spacer portion 123 is too large, the first spacer portion 123 will be located close to the first opening 107, increasing the risk of the first spacer portion 123 falling into the first opening 107. In this embodiment, the size of the first spacer portion 123 is designed to be smaller. Under the same PPI, the spacing between the first spacer portion 123 and the first opening 107 is increased, reducing the risk of the first spacer portion 123 falling into the first opening 107, thereby improving the yield of the display panel.

[0147] At least one third opening 109 is added in the light shielding layer 106 to increase the transmittance of the first area 102. If the size of the third opening 109 is too small, it is not conducive to the transmittance of the first area 102. In this embodiment, the size of the third opening 109 is designed to be larger, which can improve the transmittance of the first area 102.

[0148] In this embodiment, the non-opening area space between the adjacent first color light emitting elements 124 and the second color light emitting elements 125 along the extension direction of the first virtual edge 129 is approximately equal to the non-opening area space between the adjacent first color light emitting elements 124 and the second color light emitting elements 125 along the extension direction of the second virtual edge 130. In other words, the space for setting the third opening 109 between the adjacent first color light emitting elements 124 and the second color light emitting elements 125 is approximately equal to the space for setting the first spacer 123 between the adjacent first color light emitting elements 124 and the second color light emitting elements 125. If the size of the first spacer 123 in the same direction is smaller than the size of the third opening 109, the size of the first spacer 123 is smaller, which is conducive to increasing the distance between the position of the first spacer 123 and the first opening 107, reducing the risk of the first spacer 123 falling into the first opening 107, and the size of the third opening 109 is larger, which is conducive to increasing the total opening area of ​​the plurality of third openings 109 in the first area, thereby increasing the infrared light transmittance of the first area.

[0149] Fig.21 is a schematic diagram of another display panel provided by an embodiment of the present invention, such as Fig.21 As shown, the display area includes the second area 110; the density of the first spacer portion 123 in the second area 110 is greater than or equal to the density of the first spacer portion 123 in the first area 102. Optionally, in the first area 102, the density of the first spacer portion 123 is less than the density of the third opening 109. Fig.21 In the figure, any one of the first color light-emitting element 124, the second color light-emitting element 125 and the third color light-emitting element 126 is specifically the positive projection of the light-emitting area of ​​the light-emitting element in the display area; the first pad portion 123 is the positive projection of the side of the first pad portion facing the pixel defining layer in the display area; the third opening 109 is the positive projection of the lower opening in the third opening in the display area.

[0150] In the display panel, the second area 110 accounts for a large area in the display area, and the first area 102 accounts for a very small area in the display area. Therefore, the first spacer 123 in the second area 110 plays a major supporting role in the display panel, while the first spacer 123 in the first area 102 with a smaller area has a smaller supporting role or effect on the display panel. Reducing the distribution density of the first spacer 123 in the first area 102 will not affect the overall supporting effect on the display panel. Based on this, the density of the first spacer 123 in the first area 102 can be selected to be less than or equal to the density of the first spacer 123 in the second area 110.

[0151] In this embodiment, the density of the first spacer portions 123 in the first area 102 is designed to be less than the density of the first spacer portions 123 in the second area 110. Exemplarily, in the display area, the first spacer portions 123 are arranged in the non-opening area space between the first color light-emitting elements 124 and the second color light-emitting elements 125 adjacent to each other in the extension direction of the second virtual edge 130, and at least one first spacer portion 123 in the second area 110 is arranged in the non-opening area space between the first color light-emitting elements 124 and the second color light-emitting elements 125 adjacent to each other in the extension direction of the first virtual edge 129.

[0152] In the display panel, the second zone 110 occupies a large area in the display area, and the third opening 109 does not need to be set between the adjacent first color light-emitting elements 124 and the second color light-emitting elements 125 in the second zone 110; while the first zone 102 occupies a small area in the display area, and at least one of the first spacer 123 and the third opening 109 needs to be set between the adjacent first color light-emitting elements 124 and the second color light-emitting elements 125 in the first zone 102. Therefore, the density of the first spacer 123 in the first zone 102 is appropriately reduced, and more setting space can be provided for the third opening 109 in the non-opening area of ​​the first zone 102, and the supporting effect on the display panel will not be affected. The first zone 102 occupies a small area in the display area, and is not only used for display, but also for light transmission through the third opening 109, so that the first functional device designed in the first zone 102 can receive and send light to the outside. Therefore, in the first area 102, the density of the first spacer 123 is designed to be less than the density of the third openings 109, which is conducive to providing more third openings 109 in the non-opening area of ​​the first area 102, improving the transmittance of the third openings 109, and facilitating improving the transmittance of the first area 102. The third opening 109 is optionally provided in the non-opening area space between the first color light-emitting element 124 and the second color light-emitting element 125 adjacent to each other along the extension direction of the first virtual edge 129.

[0153] However, in other embodiments, the density of the first spacer parts in the second region may be equal to the density of the first spacer parts in the first region; and / or, in the first region, the density of the first spacer parts may be equal to the density of the third openings.

[0154] Fig. 22 is a schematic diagram of another display panel provided by an embodiment of the present invention, such as Fig. 22As shown, the optional light-emitting element 105 includes a first electrode 131, a second electrode 132, and a light-emitting layer 133 located between the first electrode 131 and the second electrode 132; the shape of the first electrode 131 is circular; along the first direction A11, the first electrode 131 covers the first opening 107. It should be noted that the circular shape of the first electrode 131 is only an example, but is not limited to this. In other embodiments, the shape of the first electrode can also be designed to be a quadrilateral, a polygon or other shapes. Along the first direction A11, the orthographic projection of the first electrode 131 covers the first opening 107. On this basis, the shape of the first electrode 131 and the shape of the lower opening of the first opening 107 can be the same or different.

[0155] In this embodiment, the optional display panel is an organic light emitting display panel.

[0156] The pixel defining layer 104 and the plurality of light-emitting elements 105 are located on the same side of the substrate 103. The first electrode 131 in the light-emitting element 105 may be an anode, and the second electrode 132 may be a cathode. The first electrode 131 may be an independent electrode, and the first electrodes 131 of two adjacent light-emitting elements 105 are insulated. The second electrode 132 may be a surface electrode, and the second electrode region corresponding to the light-emitting element 105 in the second electrode 132 is defined as the second electrode 132 of the light-emitting element 105, and the second electrodes 132 of two adjacent light-emitting elements 105 are electrically connected. However, in other embodiments, the design and position of the anode and the cathode are not limited thereto.

[0157] The light-emitting layer 133 is located between the first electrode 131 and the second electrode 132. If the first color light-emitting element 124 is a red light-emitting element, the light-emitting layer 133 of the first color light-emitting element 124 can be configured to include a red light-emitting material; if the second color light-emitting element 125 is a blue light-emitting element, the light-emitting layer 133 of the second color light-emitting element 125 can be configured to include a blue light-emitting material; if the third color light-emitting element 126 is a green light-emitting element, the light-emitting layer 133 of the third color light-emitting element 126 can be configured to include a green light-emitting material. But not limited thereto.

[0158] It can be understood that a first functional layer may be further included between the first electrode 131 and the light-emitting layer 133 in the light-emitting element 105, and a second functional layer may be further included between the second electrode 132 and the light-emitting layer 133. If the first electrode 131 is an anode and the second electrode 132 is a cathode, the first functional layer may include at least one of a hole injection layer, a hole transport layer and an electron blocking layer, and the second functional layer may include at least one of an electron injection layer, an electron transport layer and a hole blocking layer. The film structure of the display panel also includes a protective layer on the side of the second electrode 132 away from the first electrode 131, etc., which will not be specifically illustrated and described.

[0159] Optionally, the display area further includes at least one metal layer between the substrate 103 and the light shielding layer 106, the metal layer including a plurality of metal parts; along the first direction A11, the third opening 109 does not overlap with the metal part. Optionally, along the second direction A12, the spacing between the third opening 109 and the metal part is greater than or equal to the first distance, wherein the second direction A12 intersects with the first direction A11. Optionally, the first distance is equal to 3 μm.

[0160] In this embodiment, a pixel circuit structure is provided between the substrate 103 and the pixel defining layer 104 of the display area, and the pixel circuit structure includes a plurality of pixel circuits, and the pixel circuits are electrically connected to the light-emitting element 105 to drive the light-emitting element 105 to display. Specifically, at least a thin film transistor array layer 202 is provided between the substrate 103 and the pixel defining layer 104, and the thin film transistor array layer 202 is used as a part of the pixel circuit structure to drive the light-emitting element 105 to display. The thin film transistor array layer 202 includes a plurality of thin film transistors. Specifically, the thin film transistor array layer 202 includes a plurality of array metal layers and an interlayer insulating layer 205, and at least one insulating layer 205 is provided between two adjacent array metal layers.

[0161] The types of transistors in the optional thin film transistor array layer 202 are diverse, and metal oxide transistors (such as IGZO TFT) and low temperature polysilicon transistors (such as LTPS TFT) can coexist. Metal oxide transistors have advantages such as low leakage current, and low temperature polysilicon transistors have advantages such as high switching speed, high carrier mobility and low power. Specifically, the thin film transistor array layer 202 includes at least 6 array metal layers and a first active layer (POLY) 203 and a second active layer (IGZO) 204. The 6 array metal layers are marked as M1, M2, M3, M4, M5, and M6 in sequence. It should be noted that Fig. 22 Only part of the film layer between the substrate 103 and the pixel defining layer 104 is shown, and other film layers are also included between the substrate 103 and the pixel defining layer 104 in the display panel, which are not specifically limited or described. Based on the specific film layer setting of the display panel, adaptive adjustments can be made according to actual production needs, such as adding or removing part of the film layer, which is not specifically limited in the embodiment of the present invention.

[0162] In this embodiment, only multiple film layers in the thin film transistor array layer 202 are used as an example for description. For any of the six array metal layers M1 to M6, the metal layer includes multiple metal parts, and different metal parts of the same metal layer may or may not be electrically connected. Along the first direction A11, the third opening 109 does not overlap with the metal part, so the external light passing through the third opening 109 will not be blocked by the metal part and can be incident on the first functional device 201, so that the first functional device 201 can sense the brightness of the external light through the third opening 109 and adjust the screen brightness.

[0163] In addition, the light actually collected and detected by the first functional device 201 includes not only collimated incident light, but also light with a certain angle range, so as to improve the detection accuracy. Usually, customers have specifications for the attenuation of the transmittance at a large viewing angle, and the requirement is that the attenuation ratio of the transmittance intensity of the 45° light compared to the transmittance intensity of the positive viewing angle light should be less than 55%. Along the first direction A11, the smaller the spacing between the third opening 109 and the metal part, the more of the large viewing angle light will be incident on the metal part and absorbed, so that the transmittance of the large viewing angle light decays faster and the reflectivity increases.

[0164] Based on this, along the first direction A11, the spacing between the third opening 109 and the metal part is designed to be greater than or equal to the first distance, so that the 45° wide viewing angle light will not be incident on the metal part and absorbed, or the 45° wide viewing angle light is only partially incident on the metal part and absorbed, so the attenuation ratio of the transmittance intensity of the 45° wide viewing angle light compared to the transmittance intensity of the positive viewing angle light will be less than 55%, and the reflectivity increase of the third opening compared to the non-hole area is smaller. It can be seen that by designing the spacing between the third opening 109 and the metal part to be greater than or equal to the first distance, the light actually collected and detected by the first functional device 201 includes not only collimated incident light, but also light with a certain angle range, which can improve the detection accuracy.

[0165] The first distance may be 3 μm. Fig. 22 As shown, along the second direction A12 , the minimum distance Da between the third opening 109 and the metal portion is greater than or equal to 3 μm.

[0166] The minimum distance Da between the third opening 109 and the metal portion may be greater than or equal to 3 μm and less than or equal to 6 μm. It is understood that if the minimum distance Da between the third opening 109 and the metal portion is greater than or equal to 6 μm, the resolution PPI is easily affected.

[0167] It should be noted that the optional third opening 109 includes: a third upper opening, a third lower opening, and a third inner sidewall connected between the third upper opening and the third lower opening; along the first direction A11, the third lower opening is close to the metal layer; along the second direction A12, the distance between the third lower opening and the metal part is greater than or equal to the first distance, wherein the second direction A12 intersects the first direction A11. In this embodiment, along the second direction A12, the distance between the third opening 109 and the metal part is specifically the distance between the lower opening of the third opening 109 and the metal part.

[0168] It should be noted that, for the second electrode 132, the second electrode 132 may be an electrode that can transmit infrared light. Alternatively, for the second electrode 132, the second electrode 132 may have a mesh corresponding to the third opening 109. Specifically, along the first direction A11, the mesh of the second electrode 132 surrounds the corresponding third opening 109, and the spacing between the mesh of the second electrode 132 and the corresponding third opening 109 is greater than or equal to the first distance.

[0169] refer to Fig. 22 As shown, at least one metal layer may include a first metal layer and a second metal layer, the second metal layer is located between the substrate 103 and the first metal layer, and the second metal layer includes a plurality of second metal portions; along the second direction A12, the spacing between the third opening 109 and the second metal portion is greater than the first distance. The first metal layer may be located between the substrate 103 and the pixel defining layer 104.

[0170] In this embodiment, the first metal layer may be a metal layer M4, the second metal layer may be a metal layer M3, and both the first metal layer M4 and the second metal layer M3 are located between the substrate 103 and the pixel defining layer 104. The second metal layer M3 is located between the substrate 103 and the first metal layer M4.

[0171] The first metal layer M4 includes a plurality of first metal parts, and the second metal layer M3 includes a plurality of second metal parts. Therefore, along the first direction A11, the third opening 109 does not overlap with the first metal part in the first metal layer M4, and along the second direction A12, the spacing Db between the third opening 109 and the first metal part in the first metal layer M4 is greater than or equal to 3μm, and this spacing Db can be the minimum spacing between the third opening 109 and the first metal part in the first metal layer M4. Similarly, along the first direction A11, the third opening 109 does not overlap with the second metal part in the second metal layer M3, and along the second direction A12, the spacing Dc between the third opening 109 and the second metal part in the second metal layer M3 is greater than or equal to 3μm, and this spacing Dc can be the minimum spacing between the third opening 109 and the second metal part in the second metal layer M3.

[0172] In this embodiment, Db is greater than or equal to 3 μm, and Dc is greater than or equal to 3 μm. On this basis, Db and Dc may be equal, or Db may be smaller than Dc, or Db may be greater than Dc.

An optional first metal layer is located between the pixel defining layer 104 and the light shielding layer 106. An optional second metal layer is located between the first metal layer and the pixel defining layer 104, or the second metal layer is located between the substrate 103 and the pixel defining layer 104.

[0174] In this embodiment, the first metal layer can be the metal layer M7, and the second metal layer can be the metal layer M3. Therefore, along the first direction A11, the third opening 109 does not overlap with the first metal portion in the first metal layer M7, and along the second direction A12, the spacing Dd between the third opening 109 and the first metal portion in the first metal layer M7 is greater than or equal to 3μm, and this spacing Dd can be the minimum spacing between the third opening 109 and the first metal portion in the first metal layer M7. In this embodiment, Dd is greater than or equal to 3μm, and Dc is greater than or equal to 3μm. On this basis, Dd and Dc can be equal, or Dd can be less than Dc, or Dd can be greater than Dc.

The electrode part 143 includes a plurality of electrically connected first meshes 141, and at least two first meshes 141 in the electrode part 143 are electrically connected through the bridge part 144.

[0178] Fig.24 The electrode portion 143 of the third metal layer 140 is shown in FIG. It should be noted that the third metal layer 140 includes a plurality of electrode portions 143 , and different electrode portions 143 are insulated from each other. Specifically, a break DK is provided between different electrode portions 143 for insulation. Fig.24 Only two fractures DK in the third metal layer 140 are shown.

The third metal layer 140 is provided with a plurality of fractures DK so that different electrode parts 143 are insulated. The position and number of fractures DK between different electrode parts 143 can be reasonably designed according to product requirements. The electrode part 143 includes a plurality of electrically connected first meshes 141, and along the first direction A11, the first meshes 141 surround at least one light-emitting element 105. In addition, Fig.25 Only a part of one electrode part 143 is shown in the film layer where the middle electrode part is located, and only a part of one bridge part is shown in the film layer where the bridge part is located.

Along the first direction A11, at least one first mesh 141 surrounds at least one light-emitting element 105; along the first direction A11, at least one second mesh 142 surrounds at least one third opening 109. It can be seen that along the first direction A11, the third opening 109 does not overlap with the third metal portion in the third metal layer 140, so that when the external light passes through the third opening 109, it will not be blocked by the third metal portion and can be incident on the first functional device 201, so that the first functional device 201 can sense the brightness of the external light through the third opening 109 and adjust the screen brightness.

[0180] Along the first direction A11, the spacing De between the third opening 109 and the boundary of the second mesh 142 is designed to be greater than or equal to the first distance, so that the 45° wide viewing angle light will not be incident on the third metal part and absorbed, or the 45° wide viewing angle light is only partially incident on the third metal part and absorbed, so that the light actually collected and detected by the first functional device 201 includes not only collimated incident light, but also light with a certain angle range, which can improve the detection accuracy. The minimum spacing De between the third opening 109 and the boundary of the second mesh 142 can be greater than or equal to 3μm and less than or equal to 6μm.

[0181] It should be noted that the mesh in the third metal layer can also be composed of multiple metal wires that cross each other. Specifically, the multiple third metal parts in the third metal layer can be divided into multiple parallel first metal wires and multiple parallel second metal wires, the first metal wires and the second metal layer are stacked and insulated, the multiple first metal wires and the multiple second metal wires cross, and then the multiple first metal wires and the multiple second metal wires cross along the first direction to define multiple meshes.

[0183] The pixel circuit 301 can be set in a variety of ways. In the present embodiment, the pixel circuit 301 is illustrated by an "8T1C" structure, wherein "T" represents a transistor and "C" represents a storage capacitor.

[0184] Along the first direction A11, the orthographic projection of the third opening 109 on the plane where the substrate 103 is located is located between two adjacent data signal lines DATA. The light emitting element 105 includes a first electrode 131. Along the first direction A11, the first electrode 131 and the data signal line DATA have an overlapping portion. For the portion of the data signal line DATA that does not overlap with the first electrode 131, the third opening 109 can be set between two adjacent data signal lines DATA, so that the orthographic projection of the third opening 109 on the plane where the substrate 103 is located is located between the two adjacent data signal lines DATA.

[0185] The third opening 109 includes a first side and a second side opposite to each other along the second sub-direction F42; along the second sub-direction F42, the spacing Df between any one of the first side and the second side and the nearest data signal line DATA is greater than or equal to the first distance. When the wide-angle light passes through the third opening 109, the risk of being blocked by the metal wire in the display panel is reduced, so that the light with a certain angle range can pass through the third opening 109 and the gap in the metal layer of the display panel and enter the first functional device 201, which can improve the detection accuracy of the first functional device 201. Df can be greater than or equal to 3μm and less than or equal to 6μm.

[0190] Fig.28 is a schematic diagram of another display panel provided by an embodiment of the present invention, Fig.29 is a schematic diagram of another display panel provided by an embodiment of the present invention, such as Fig.28 and Fig.29 As shown, in the optional first area 102, the light shielding layer 106 further has at least one fourth opening 161, and the pixel defining layer 104 has at least one fifth opening 162; along the first direction A11, the fourth opening 161 overlaps with the fifth opening 162, and the fourth opening 161 does not overlap with the first opening 107. Fig.28 The first area 102 , the fourth opening 161 , the third opening 109 , the second opening 108 , and the first opening 107 are all orthographic projections of the structures along the A11 direction. Fig.29 The figure shows the overlapping relationship between the fourth opening 161 and the fifth opening 162 , and does not represent the actual size relationship. The relationship between the two can be designed to be greater than, less than or equal to each other according to product requirements.

[0191] It should be noted that, for the fourth opening 161, along the second direction A12, the spacing between the fourth opening 161 and the metal portion in any metal layer is greater than or equal to the first distance. That is to say, along the first direction A11, the metal wire of any metal layer between the substrate 103 and the light shielding layer 106 is designed to be wound around the fourth opening 161 to prevent the metal wire from blocking the light passing through the fourth opening 161. Similarly, along the first direction A11, the metal wire of any metal layer between the substrate 103 and the light shielding layer 106 is designed to be wound around the fifth opening 162 to prevent the metal wire from blocking the light passing through the fifth opening 162.

[0192] In this embodiment, at least one fourth opening 161 is added to the light shielding layer 106, and at least one fifth opening 162 is added to the pixel defining layer 104. The shape of the fourth opening 161 can be polygonal or circular. Fig.28 As shown, the optional fourth opening 161 is in the shape of a rounded rectangle, but is not limited thereto.

[0193] Specifically, at least one third opening 109 and at least one fourth opening 161 are provided in the area outside the second opening 108 of the light shielding layer 106 , and the light emitted by the light emitting element 105 is emitted through the second opening 108 .

[0194] The optional fourth opening 161 is a light transmission opening in the 550nm band; the third opening 109 is a light transmission opening in the 940nm band. Specifically, the first zone 102 includes an IR hole 102a and a LS hole 102b, the IR hole 102a is an infrared light projection hole, the LS hole 102b is a visible light projection hole, the IR hole 102a is provided with one or more third openings 109, and the LS hole 102b is provided with one or more fourth openings 161.

[0195] Specifically, the third opening 109 is a light-transmitting opening in the 940nm band. Along the first direction A11, the third opening 109 does not overlap with the first opening 107, and the orthographic projection of the third opening 109 on the pixel defining layer 104 is located in the non-opening area of ​​the pixel defining layer 104, that is, the pixel defining layer area corresponding to the orthographic projection of the third opening 109 is not opened. Therefore, the third opening 109 will not affect the light-emitting area of ​​the light-emitting element 105, thereby ensuring the normal display function of the display panel. And at least one color filter in the color resist layer 111 is filled in the third opening 109, so that the third opening 109 has a high transmittance in the infrared light band, but the third opening 109 basically does not transmit visible light. Therefore, the first functional device 201 in the first area 102 may include an infrared light sensor 201a for sensing infrared light, and the infrared light sensor 201a overlaps with at least one third opening 109 along the first direction A11.

[0196] Specifically, the fourth opening 161 is a light transmission opening in the 550nm band. Along the first direction A11, the fourth opening 161 does not overlap with the first opening 107, and the orthographic projection of the fourth opening 161 on the pixel defining layer 104 overlaps with the fifth opening 162. That is to say, the pixel defining layer area corresponding to the orthographic projection of the fourth opening 161 has a corresponding fifth opening 162. Therefore, the fourth opening 161 will not affect the light-emitting area of ​​the light-emitting element 105, ensuring the normal display function of the display panel. And the color resist layer 111 does not fill the fourth opening 161, and the fourth opening 161 can pass through the visible light, and the specific visible light can enter the inside of the display panel through the fourth opening 161 and the fifth opening 162, or the light emitted by the first functional device 201 is emitted to the outside of the display panel through the fifth opening 162 and the fourth opening 161. Therefore, the first functional device 201 in the first area 102 can also include optical devices such as a camera 201b that senses visible light, and the camera 201b overlaps with at least one fourth opening 161 along the first direction A11.

[0197] Further, along the first direction A11, the fourth opening 161 may overlap with the fifth opening 162, or, according to product requirements, the orthographic projection of the fourth opening 161 may be designed to cover the fifth opening 162, or, according to product requirements, the orthographic projection of the fifth opening 162 may be designed to cover the fourth opening 161.

[0198] Specifically, after the process of the color resist layer 111, a photoresist layer 118 will be coated on the color resist layer 111, and the optional transparent photoresist material will be directly filled in the fourth opening 161, so the fourth opening 161 can be used as a visible light sensitive opening to transmit visible light. Specifically, the fourth opening 161 filled with transparent photoresist material has a high transmittance of 550nm and meets the transmittance requirement of visible light. The optical device set in the first area 102 can include a light sensor. Along the first direction A11, the light sensor overlaps with at least one visible light sensitive opening, and the visible light sensitive opening allows visible light to pass through. Then, the light sensor can adjust the screen brightness of the display device according to the brightness of the surrounding light. Adding at least one fourth opening 161 in the first area 102 can improve the transmittance of the first area 102. While ensuring the normal display of the first area 102, it also enables the first area 102 to achieve a better light transmission effect, thereby improving the sensing sensitivity and accuracy of the light sensor in the first area 102, and achieving a better brightness adjustment effect.

[0199] It should be noted that the first area 102 includes multiple fourth openings 161, and transparent photoresist material can be selected to fill the multiple fourth openings 161, so that the first area 102 can realize the visible light transmission function, which is conducive to setting an under-screen camera or other optical device for sensing visible light in the first area 102.

[0200] In this embodiment, a fourth opening 161 is added to the light shielding layer 106, and a corresponding fifth opening 162 is added to the pixel defining layer region corresponding to the fourth opening 161. The third opening 109 can be used to transmit infrared light, and the fourth opening 161 can be used to transmit visible light. Based on this, the infrared light transmittance and visible light transmittance of the first area 102 can be increased, so that the first area 102 includes not only the IR hole 102a for sensing infrared light but also the LS hole 102b for sensing visible light.

[0201] Optionally, along the first direction A11 , the fourth opening 161 does not overlap with the color filter in the color resist layer 111 , and the fourth opening 161 does not overlap with the light emitting element 105 .

[0202] In this embodiment, in the process of forming the color resist layer 111, the color resist material may be filled in the second opening 108 and the third opening 109, but the color resist material does not fill the fourth opening 161. Therefore, along the first direction A11, the fourth opening 161 does not overlap with the color filter in the color resist layer 111, so that the fourth opening 161 can pass visible light.

[0203] Along the first direction A11, the fourth opening 161 does not overlap with the first opening 107. Specifically, the fourth opening 161 does not overlap with the light emitting element 105, and the second opening 108 overlaps with the first opening 107. Therefore, the light emitted by the light emitting element 105 is emitted from the second opening 108 in the light shielding layer 106, and the large-angle light emitted by the light emitting element 105 will be blocked by the non-opening area of ​​the light shielding layer 106 and the color filter in the third opening 109, and no light will leak. Even if the light emitting element 105 leaks light from the fourth opening 161, since the area of ​​the fourth opening 161 in the first area 102 is very small, the influence of the light intensity leaked from the fourth opening 161 on the display effect of the display panel can also be ignored.

[0204] Optionally, along the first direction A11, the area of ​​the orthographic projection of the fourth opening 161 is less than or equal to the area of ​​the orthographic projection of the third opening 109. Optionally, the pixel defining layer 104 includes: a plurality of first spacers 123; along the first direction A11, the fourth opening 161 does not overlap with the first spacers 123. Optionally, along the first direction A11, the orthographic projection of the fourth opening 161 is located in the fifth opening 162.

[0205] In this embodiment, along the first direction A11, a fifth opening 162 is provided in the pixel defining layer region where the orthographic projection of the fourth opening 161 is located, and the pixel defining layer region where the first spacer portion 123 is located is a non-opening area of ​​the pixel defining layer 104, so along the first direction A11, the fourth opening 161 does not overlap with the first spacer portion 123.

[0206] A fourth opening 161 and a third opening 109 are added to the light shielding layer 106. Along the first direction A11, the orthographic projection of the third opening 109 and the first spacer portion 123 are both located in the non-opening area of ​​the pixel defining layer 104. Along the first direction A11, a fifth opening 162 is provided in the pixel defining layer area corresponding to the orthographic projection of the fourth opening 161. Optionally, along the first direction A11, the third opening 109 does not overlap with the first spacer portion 123. Therefore, along the first direction A11, the orthographic projection of the third opening 109, the fifth opening 162 and the first spacer portion 123 jointly occupy the pixel defining layer area outside the first opening 107 in the pixel defining layer 104.

[0207] If the area of ​​the orthographic projection of the fourth opening 161 is too large along the first direction A11, the area of ​​the corresponding fifth opening 162 will be adaptively increased, which will occupy the station space of the first spacer 123 and / or the third opening 109. Based on this, the station space of the first spacer 123 is occupied, which will cause the distance between the first spacer 123 and the first opening 107 to be too close and easy to fall into the first opening 107, affecting the display effect, or reducing the size or number of the first spacer 123 in the first area 102 will reduce the supporting effect of the first spacer 123. For the station space of the third opening 109, reducing the size or number of the third opening 109 will affect the infrared light transmittance of the first area 102.

[0208] For example, taking a mobile phone of conventional size as an example, the light shielding layer 106 of the display panel of the mobile phone has a fourth opening 161, and the opening size of the fourth opening 161 can be 8.63 μm*12.46 μm; the opening area of ​​the fifth opening 162 can be greater than 76 μm 2 , and / or, the opening area of ​​the fifth opening 162 may be greater than the opening area of ​​the fourth opening 161; the opening area of ​​the third opening 109 may be greater than 91 μm 2 .

[0210] It can be seen from this that if the area of ​​the fourth opening 161 is designed to be smaller, the area adaptability of the corresponding fifth opening 162 is reduced, which can reduce the space occupied by the fifth opening 162 in the pixel defining layer 104, which is beneficial to provide more standing space for the first spacer 123 and the third opening 109 in the pixel defining layer 104. The display effect of the display panel and the light transmittance of the first area 102 are guaranteed.
